My C65 Chevy (27500 LB) hauls regularly an 8 ton backhoe on a 9 ton trailer. Engine is 427 gas. Hills are slow both directions, but the rest of the chassis does OK. My young friend borrowed it to take several loads of scrap to the salvage yard. He towed his grandfather's 20 ton. After, I learned he'd peaked at a weight slip of 42,000. I was a bit upset with him.
